Ex: Hot / Dry
Ex: Cold / Moist

(high to low)



Or Thumbs UP!

The lines show what type of wind may occur


Divide your paper into four equal sections
Read the FRONTS section on page 127 & 128
Label each section with the 4 fronts:
◦ Cold Front, Warm Front, Occluded Front, Stationary
Front



Describe what happens at each front & what
type of weather occurs
Draw a picture of each front & use Red & Blue
colored pencils to add color.
INCLUDE THE SYMBOL OF THE FRONT!!!!!!

Fronts move in the direction they are headed!

Tips: The blue triangles on a cold front= think of icicle


Q: What types of temperatures are left after a cold front
moves through?
Q: What direction is this cold front moving?
Hint: The half circles on a warm front= think of the sun


Q: What types of temperature are left after a warm front
moves through?
Q: What direction is this warm front moving?



Neither cold nor warm
air advances.
Hint: Think of the line
of scrimmage in a
football game when
both teams equally
push against each
other
OR a Stationary Bike!

Hint: The 2 C’s in oCCluded for 2 cold air
masses.
Cold air masses close out the warm air from
the surface.
The only front that includes ____ air masses.
( How many air masses are involved?)
